The sahy9/apum23 mutants are sensitive to various salt stresses. a-c Developmental arrest of the sahy9 mutant seedlings. Col-0, sahy9/apum23 and apum23–2 were grown for 10 days on basal medium supplemented with 150 mM KCl (a), 150 mM NaNO3 (b), or 15 mM LiCl (c). d-f Bleached cotyledons of the sahy9/apum23 mutants. Seeds were grown on basal medium supplemented with 150 mM KCl (d), 150 mM NaNO3 (e), and 15 mM LiCl (f) for 30, 30, and 20 days, respectively. Three biological repeats, each with approximately 100 seeds, were performed, and consistent results were obtained. Scale = 1 cm
